Optimizing your SAG mill operation
· In the past, when primary, secondary and tertiary crushers fed material directly to large ball mills, the energy efficiency of the concentrator was determined for the most part by the ball mill operation, whereas now the energy efficiency of a plant often rests largely on the SAG mill operation. As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills.
